Research on the Innovative Path of New Quality Productivity to Empower Traditional Measurement

烟气含湿量是工业排放监测、燃烧效率优化及环保合规性评估的关键参数。不同工况下对烟气湿度的测量需求差异显著，阻容法、重量法和干湿球法作为主流测试方法，各有其技术特点及适用场景。本文结合文献与工业实践，系统分析三类方法的原理、性能特征及适用范围，为仪器选型提供科学依据。Flue gas moisture content is a key parameter for industrial emission monitoring, combustion efficiency optimization, and environmental compliance assessment. The measurement requirements for flue gas humidity under different working conditions are significantly different, and the resistance and capacitance method, gravimetric method and wet and dry bulb method are the mainstream test methods, each with its own technical characteristics and applicable scenarios. In this paper, the principles, performance characteristics and scope of application of the three types of methods are systematically analyzed by combining literature and industrial practice, so as to provide a scientific basis for instrument selection.
